20. MAIN CONCEPTS

21. INTEGRATION-ORIENTED
• Rhino
- Interaction with Java (APIs and objects)
- Helma, Persevere, Narwhal, RingoJS, Sun Phobos...
• JScript .Net
- Interaction with MS .NET (APIs and objects)
- IronJS, Node.NET

22. COMMON JAVASCRIPT
• Ubiquity not only for ECMAScript
• Server missing APIs
• Web Applications 1.0
• Asynchronous & Synchronous
• Working Groups:
- CommonJS
- WHATWG
- W3C
- ECMA TC39

23. ASYNC. EVENT-BASED
• Browser Event-Loop on the Server
• An Event Loop in one single thread
• Cooperative («one at a time») with async. callbacks
• Node.js (V8), SpiderNode, RhiNodeII, Node.NET

24. SINGLE vs MULTI THREADING
One context per thread

25. SINGLE vs MULTI THREADING
One context per thread
SINGLE MULTI
• Low memory usage • Vertical scalability (multi-core)
• Potentially handle lot of requests • Thread-safety for concurrent access
• Cooperative • Preemptive: Parallel code execution
• Shared context • Allow Synchronous APIs
• Use mostly one core • Uses easily all available cores

26. DATABASE-DRIVEN
• Document Store
- CouchDB, MongoDB
• Object Store
- Wakanda
• Push Store
- APE

27. APIS

28. COMMONJS
• Modules
• Packages • Binary
• Promises • File
• System • JSGI
• Unit-Testing • Stream
http://wiki.commonjs.org/wiki/CommonJS

29. NODE ASYNC APIS
• Buffer • Process
• Events • Streams
• File • Timers
• Net • ...
• OS
http://nodejs.org/docs/v0.5.5/api/

30. W3C / HTML5
& OTHER STANDARDS
• Console • Structured clones
• Blob, Blob URL* • Typed Arrays*
• DataView* • Web Sockets
• File / FileSystem • Web Storage
• Modules* • Web Workers
• Progress Events • XHR 2

31. PACKAGES & MODULES
• github: CommonJS modules in forks (Persevere, Narwhal, RingoJS, ...)
• NPM: Node Package Manager (3600+ packages)
• CPM: CommonJS Package Manager (new)
• PINF: Universal module loader
